Mine is OK, not slower at startup, i actually find it a little bit more responsive at startup.. BUT i do complain to the fact that my hidden updates disappeared.. and i still haven't been able to get them back.. it took 17 minutes to install, other than that.. no major differences

LoL
what a surprised that you'r hidden updates disappeared ? >>> NOT!!!! because sp1 includes those small hidden updates and all other updates.
Hm, i thought you knew it.

I don't think that's the answer.. because if the SP1 includes .NET Framework 4.0 Client Profile and Windows Live Essentials 2011, then it would show up as an installed program under Programs and Features and it isn't that's the kind of "hidden updates" i was talking about.. not the hotfixes..

Leakers seem to have gotten their hands on what may be the final Windows 7 Service Pack 1/Windows Server 2008 R2 SP1 builds.
(I had heard rumors that Microsoft had put the finishing touches on SP1 in December, but don’t know for sure whether that is true.)
Microsoft officials are not saying whether the latest leaked version is the “real” SP1 release-to-manufacturing version. As usual, the advice to customers is to wait for the official Microsoft-provided SP1 before deploying to avoid potential malware and security risks.
Unlike previous first service packs of Windows — which were an absolute must-have for many business users before they’d even think about deploying the latest Windows variant — the coming SP1 feels a bit anti-climactic. (At least on the client side.)
Microsoft officials have said not to expect any new features in Windows 7 SP1. (There was a Microsoft blog post last year that acknowledged there would be some “feature enhancements” in SP1 around federation services, audio devices and printing.) They’ve also said to expect a couple of new virtualization updates in the server version of SP1, specifically RemoteFX and a dynamic-memory adjustor for Hyper-V.
